LOUIS HELLNER, OFNEWV YORK, N. Y.

STALL-FLOOR.

SPECIFICATION forming part of Letters Patent No. 419,670, dated January21, 1890.

Application filed April 4. 1889. Serial No. 305,922- (No model.)

1 To aZZ whom it may concern:

Be it known that I, LOUIS HELLNEB, a citizen of the United States,residing at New York city, in the county of New York and State of NewYork, have invented new and useful Improvements in Stalls, of which thefollowing is a specification.

This invention relates to an improvement in stalls by which the gratingin the stallfloor is made cheap, durable, and easy of repair, as setforth in the following specification and claim and illustrated in theaccompanying drawings, in which Figure 1 is a plan view of a grating ina stall-floor. Fig. 2 is a section along a: a", Fig. 1. Fig. 3 is asection along y y, Fig. 1.

Similar letters indicate corresponding parts.

In the drawings, the letters A A indicate the sides of a stall. Into asuitable recess in the stall-flooris let the rectangular frame B,preferably of metal or durable material. The frame B communicates with adrain 0, so that moisture will drain off from the stallfloor through thedrain 0. Said frame B has angular mortised seats to receive the bars D,which are angular in cross-section, so as to correspond to the mortisedseats in the frame. The bars D are shown quadrangular in crosssection;but of course they might be made hexagonal or otherwise angular incross-section, the mortised seats for said bars of course correspondingwith the bars. By having the bars D angular in cross-section said barswill not turn in their seats, as might be the case if the bars werecylindrical. Byhaving the mortised seats for the bars formed angular,and by having the various faces of said bars formed to correspond to theangular mortised seats, when one face of a bar is worn or injured saidbar can .be readjusted or reversed in the frame, so as to expose a freshface of the bar to use. The bars can thus be made to last a long time,thus securing oheapness and durability.

To prevent the bars being accidentally removed from the frame, screws Eare shown engaging the bars so as to clamp or look the bars in place.The screws are shown seated in recesses in the frame B, so that a key isrequired to loosen the screws. To reach the screws the frame B is simplylifted out of the stall-floor, so as to expose the side of the framewhere the screws are situated. By making the metal work of non-corrosivematerial such as galvanized iron-cleanliness and durability of the metalwork can be secured. By having each screw E engage a bar at one end thebar will not have to be drilled or perforated to receive the screw.

WVhatI claim as new, and desire to secure by Letters Patent, is

1. A stall having in its fioora rectangular frame provided in itsuppermost edges with mortised seats, in combination with a series ofindependent angular bars separately and detachably held at their ends inthe mortised seats and adapted to be removed, reversed, and replaced,substantially as described.

2. A stall having in its floor a rectangular frame provided withmortised seats, in combination with a series of disconnected independentangular bars detachably arranged at their ends in the mortised seats andeach adapted to be removed, reversed, and replaced, and aseries ofscrews passing through the frame and respectively engaging the bars,substantially as described.

In testimony whereof I have hereunto set my hand in thepresence of twosubscribing witnesses.
